CHARLES W. WARNER, QF MIDDLETOWN, CONNECTICUT AUTOMATIC BOAT BAILER Application filed December 23, 1929. Serial No. 415,879.

This invention relates to those devices which are designed to be attached to motor boats, motor cruisers, auxiliary sailboats and boats of like character, being particularly adapted for use with speed boats and outboard motor boats, for the purpose of automatically draining all water from the bilge of the boat to which it is applied by means gt suction induced by the movement of the oat.

The object of the invention is to produce a device of this character'which is simple, durable, safe, easy to install and convenient to manipulate.

In the accompanying drawings 'Fig. 1

shows a side view of the deviceclosed and in position of use. Fig. 2 is a vertical section of thesame. Fig. 3 is a View of the body looking from the back.

The body of the device, which is desirably made of bronze so that it may be used in either salt or fresh water, has a tubular stem 1 that is designed to be inserted in a hole bored through the planking 2 near the lowest point of the hull which is usually adjacent to the keel near the stern of the boat. The body has a flange 3 shaped to fit the outside of the planking and the section within the hull is exteriorly threaded. Turning on this threaded section is a flanged nut 4 which is adapted to be screwed down so as to clamp the planking between the exterior flange and the interior nut. side wall near the upper end of the tubular stem are inlet ports 5. The lower section of the body is rounded and curved and when the device is located in place of use theopening from this curved section is directed toward the stern of the boat. I

A flapper valve 6 is arranged to close the discharge opening, the valve preferably having lugs 7 that are pivoted to the sides of the body so that it will normally close by gravity.

Th rough the .lneaded upon the upper end at the stem is acap 8, which when screwed up exposes the inlet ports and when screwed down closes these ports. A packing 9 is set into a recess inthe top of the flanged nut so that a tight joint will be made when the cap is screwed down.

Bilge water enters the ports from the bilge and is drawn outward by the suction of the water flowing past the out-let'on the exterior of the hull. The flapper valve is automatically dragged open to allow this and closes when the boat is stationary or running slowly. The flapper valve and its seat are ground so that practically a. tight joint is formed, the pressure of-the water closing the flapper valve when the boat "is idle. When the boat is anchored or stopped for any length of time the cap is screwed down upon the stem over the ports against the packing carried by the nut to prevent the inward leakage of water should any pass the flapper valve.

The invention claimed is:

1. An automatic boat bailer comprising a body having an exteriorly threaded tubular upper section with radial intake ports, a

curved lower section with a rearwardly facing discharge opening and an integral encircling flange betweenthe upper and lower sections, said flange being designed to fit the exterior of the hull planking, a valve hinged to the lower section and designed to open and close said discharge opening, a flanged nut threaded upon the upper section, and designed to be screwed down against the interior of the hull plankingfand a cap threaded upon'the upper section and adapted to expose and close the radial ports in said section.

2. An automatic boat bailer comprising a body having an exteriorly threaded tubular upper section with radial intake ports, a curved lower section with a rearwardly fac-v ing discharge opening and an integral encircling flange between the upper'and lower sections, said flange being designed to fit the exterior of the hull planking, a valve hinged to the lower section and designed to open and close said discharge opening, a flanged nut threaded upon the upper section, and designed to be screwed down against the interior of the hull planking, a packing set into said nut, and a cap threaded upon the upper sec tion and adapted to be screwed up to expose the intake ports and down against said packing to close said intake ports.
